混杂纤维复合材料的平面剪切性能

Study on In-plane Shear Property of Hybrid Fiber Composites

研究了基体韧性和铺层方式对玻璃纤维、碳纤维及其混杂纤维复合材料平面剪切性能的影响。结果表明 ,玻璃、碳及其混杂纤维复合材料的平面剪切应力 -应变曲线均具有非线性特征 ;在脆性基体中选用混杂结构 ,其复合材料的剪切性能具有正的混杂效应。

In the article, we studied the effect of matrix toughness and stack sequence on in-plane shear properties of the composites reinforced with glass fiber, carbon fiber and hybrid fiber. The results shows that the stress-strain curves of the composites were nonlinear and the hybrid fiber composites had a positive hybrid effect when the brittle matrix was used.
